We build Lofts. We build Extensions. We undertake conversions. Our Terms and conditions apply as shown in our starter packs.

Builders charge between £18,428 (GS Fabric Ltd based in E2) and £20,564 (Q Lofts and Extensions based in EC1R) in EC1V to build a garage, but these costs are only estimates.
Comparing extension builders estimates for building a garage gives you an idea of who will be better value, but the best way to compare costs is to get actual quotes.
